<span class="quote">&gt; Source/WebCore/ChangeLog:14
&gt; +        Test: fast/forms/onchange-select-check-validity.html
&gt; +
&gt; +        When selecting an option in a &lt;select&gt; with validation that also has an onchange listener, calling
&gt; +        checkValidity() for the select within the onchange handler would produce incorrect results and (on
&gt; +        a debug build) crash at an assertion. This is because the change events were being dispatched before
&gt; +        form validity was updated. Making the validation step come before the change event dispatch fixes
&gt; +        this issue.</span >

Normally the Test line comes last.

<span class="quote">&gt; LayoutTests/fast/forms/onchange-select-check-validity.html:17
&gt; +        select.onchange = showFormValidity;
&gt; +        select.addEventListener(&quot;change&quot;, showFormValidity);</span >

I think these two lines do the same thing. You only need one of them.</pre>
